Anyone had any experience with the chinook carbon booms? Looking for a replacement 180 x 230, with a little less weight than the alloy.
Chinook have a 180 x 246 for the right price.
Any weak spots etc.
A freind just informed me of his troubles with the tail clamps on a certain brand, which turned me off that one. 
Are you referring to the new Pro 1 Carbon. I am also waiting to see one in the flesh before I make my mind up. Stu Bell has a shipment in soon.
I bought a new one approx 12mths ago. it's a 170-237 carbon slalom. The boom clamp is crap[}:)]. If you tighten it it still has a wobble and slips down the mast sometimes.. The grip started peeling off after the first sail and now i glue it back on every few sails and it keeps coming off. I should have taken it back to the shop i got it from but i didnt get around to it and now it's too late.
As far as weight goes its as light as a feather and the wide tail end is great. i put up with it but i won't go Chinook again. My Areon carbon is light yrs better but is lot heavier.
aarghh crap 
Thanks Bender, back to plan "A". You've probably just saved me a dollar or two 
I have the same boom and bought it in late 2009. I have had no problems with it and I bought it because I was sick of snapping aluminium booms every year.
So far so good, and I haven't had the problem of clamp slippage. It helps that I am now using Ezzy RDMs as they have a nice rubber spacer to make an RDM into SDM size for the boom.
The clamps do have this unusual pivot setup where the clamp itself pivots on a pin so that the clamp is not in a fixed position relative to the rest of the boom. It took a while to get used to, but I don't notice it anymore.
The cover is peeling at the front, but for me this is where I always start tearing booms, and all my booms have had this.
I do wish they marked the measurements on the foam though, just so I can cut down the time it takes me to adjust my harness lines each time.
Also, the wide tail on this is good. I think from what I have read that they changed from a narrow tail to the wider tail, and it definitely suits modern sails.
Just had a chat to the shop and found that this year they're using a new mast clamp. Same one as used on the aeron. 
Have you seen mine? that's about a year old, none of Bender's problems. But the stainless bolts started to rust.
Just to mess with your head Pepe, I won't tell you how many times I've got to raise my boom in a session cause the useless head keeps slipping.
Have had to glue a layer of rubber unto the cup to attempt to get it to stay put.
de las chynook carbon dat y have tested was not stiff et all
espesiely wen you have tested de x9 or de maui sails booms
also heard alod of good over de al 360
I have the Chinook 170-236, its never slipped, on rdm and sdm masts.
I use a rubber shim on the rdm's though which give a better grip.
Stiffnesswise they arent much better than a decent alu boom.
When this one goes I might go back to a decent quality alu one as they seem to have got a lot better recently
i own a chinook 170-236 carbon boom
has adjustable front end which i do not like as feels a little less secure.
also screw in front end has come loose so i cannot use till i find tool to tighten it, also screw is rusting badly.
what i like is extra long extension on chinook, which i swapped over to my aeron 145-185 boom, which now extends to 2 metres.
as for booms slipping on masts,it's the boom clamp combo with mast.
i have slippage with booms all the time,but on certain masts with wider diameter no slippage
Those that are using the Chinook boom,is it the new version.?? The Pro 1 carbon.
The head looks as if it has been changed and from what I can see on web pictures it looks the same as used on the latest Aeron. The only difference is the Aeron has rubber inserts on the lever and a name plate. If you look on the Chinnok head it has a "bow tie" moulding on the front of the head which matches the shape of the Aeron name plate. Coincidence ! There are a few other similarities such as the rubber insert at mast connection,sdm/rdm insert,lever profile. I hope to see one soon to compare with the Aeron
Lets hope they have changed the bolts to real 316. Shame to ruin what might be a good product for the sake of a few cents on good stainless fasteners.
In case you have not found it yet Pepehttp://www.al360.it/windsurf/index.htm
